FIELD: technological processes.
SUBSTANCE: according to the method, the construction length of optical cable is subjected to temperature cycles, for which the drum with construction length of the optical cable is placed in a climatic chamber in which thereafter several temperature cycles are performed, wherein, at the beginning of each cycle, a predetermined positive temperature is set in the climatic chamber, then during the cycle, the temperature in the climatic chamber is gradually lowered to the set negative values, then the temperature is subsequently increased in the climatic chamber to the set positive values, after which the cycle is completed, wherein the transition from one set temperature value to the other is carried out for a predetermined time interval and each set temperature value is set in the climatic chamber for a predetermined time interval.
EFFECT: extending the service life of modular optical cable.
